Hi everyone,
I would like to get your opinion about two model approaches for Time Series.
That is a logical data model and the final physical model could differs.

Option 1.


Option 2.

Please omit some attributes specific to our scenario. The discussion is if a time series should be defined as an entity with an Id, a source and the data points in a second entity with the key-value pairs (timestamp -> value) plus unit and some tags, or (option 2) rything in a single entity define by the timestamp, metric and source; the combination of these 3 attributes gets a value with a unit.

Any comment would be highly appreciated.
Kind regards,
Paul
